Oh please. How many of us have a camera and mic following us every minute to catch every mutter we make? "Professional" behavior is great--I wouldn't utter a curse in a meeting or presentation, but if a camera were following every little thing I did, yes, it would catch some salty words in my own office when something goes amiss. Not loudly mind you, but we're talking here about someone who has a mic on them to pick up nearly every whisper.
(And what laws are being broken here, that Tiger and people like him think they're above?)
As a broadcaster, you too have a mic in your face when at work. You just can't let loose with some vulgar statement, because something goes wrong during your show. You have to wait for a spot break when you have the mic off to let loose, if you need that sort of release. In the industrial work world, that has become very politically correct in the 21st century, you could find yourself with a pink slip for using certain vulgar words, etc, that are overheard by fellow employees and they file a complaint, even if you weren't talking to them, but were muttering to yourself. In the work place you do not have the freedom to say anything you'd like. That's the reality for most people, so why should Tiger or any other sports or entertainment person have a special dispensation to bring that sort of trash talk into our living rooms? These folks are making money by us watching their various sporting events on TV. They are guests in our homes. Would they want someone saying that sort of stuff in front of their children in their living rooms? If they don't care then they are not very good parents.
The FCC decency laws might be being violated by what Tiger is muttering on the air, but I was referring to when sports figures become famous and multi millionaires that they seem to violate drinking and driving laws, drug laws, etc and then expect to get treated differently than the average citizen, because of who they are. The Hollywood crowd has the same attitude (Paris Hilton, etc)
